I'd read an article on a study into the effectiveness of nicotine on ADHD. It also claimed that bare nicotine just by itself was difficult to become addicted to. Considering I haven't heard anything else on the topic aside from that one article, was that just bunk science or is there any truth to the matter?

I just heard a theory proposed that spacetime is a type of superfluid, which could potentially be the elusive "theory of everything". Is there any validity to this idea?
